Scientists have created the most accurate 3D map of areas in our milk career so farwhere the stars arise. This was stated on its website by the European Space Agency (ESA), according to which it extends up to 4000 light -years away from the Sun and is based on long -term observations of the Gaia space spacecraft. APA reported on Wednesday.
- Scientists have created the most accurate 3D map of stars.
- Mapping dates back to 4000 light -years from the Sun.
- The data used come from the Gaia probe observations.
ESA explained it is In fact, very difficult to observe areas in the universe where stars arise because they are usually hidden dense behind the clouds of gas and dust. Although even the Gaia probe cannot see through these clouds, it can measure how much light emitted by stars is blocked by dust. Based on this, scientists can create 3D dust distribution maps and determine the amount of ionized hydrogen, which is an indicator of emerging stars.
The new 3D map is based on observations of 44 million “ordinary” stars and 87 stars type O, which are 15 to 90 times more massive and approximately 30,000 times brighter than the sun. Their radiation is so intense that it can ionize the surrounding hydrogen.
Different telescopes have already observed the stars area, but no one has yet known how they might look in a 3D perspective. “So far, there was no model of the layout of ionized gas in the local milk distance, which would be so well with the observations of the sky from other telescopes,” He quotes ESA astronomer Lewis McCallum of the British University of St. Andrews. “Therefore, we are convinced that our view from above and our videos are a good approximation of what these clouds look like in 3D,” added.
